Abstract: A method and a device for producing honeycomb particles capable of absorbing harmful molecular elements are disclosed. A chemical element having a crystal structure is dissolved in water in a certain percentage to form a chemical element solution, and then it is pressurized. The pressurized chemical element solution is sprayed out in mist form toward a forming mirror by a high-pressure nozzle of a spray tube. When the chemical element solution in mist form contacts the heated forming mirror, the moisture quickly bursts and evaporates to form fine particles. The dried fine particles of the chemical element are made to fall by the high frequency vibration and are collected. Accordingly, the chemical element having a crystal structure is formed into fine particles having many air holes, increasing the area for chemical reaction and further increasing the efficiency of absorption of harmful elements such as various toxic elements or bacteria.

Abstract: Devices, systems, and methods are directed to the use of vapor phase change in binder jetting processes for forming three-dimensional objects. In general, a vapor of a first fluid may be directed to a layer of a powder spread across a build volume. The vapor may condense to reduce mobility of the particles of the powder of the layer. For example, the condensing vapor may reduce the likelihood of particle ejection from the layer and, thus, may reduce the likelihood of clogging or otherwise degrading a printhead used to jet a second fluid (e.g., a binder) to the layer. Further, or instead, the condensing vapor may increase the density of the powder in the layer which, when repeated over a plurality of layers forming a three-dimensional object, may reduce the likelihood of slumping of the part during sintering.

Abstract: A method of producing a curved plate by additive layer manufacture is provided. The method includes building up the plate layer-by-layer such that a first layer forms a bottom edge of the plate and the plate is additively extended upwards therefrom by subsequent layers such that a last layer forms an opposing top edge of the plate. In this way, spaced, first and second lateral edges of the plate each grow layer-by-layer to extend between respective ends of the bottom and top edges. The plate thus built up arches over from the bottom edge to adopt a curved shape on cross-sections through the plate normal to the bottom edge.
